Electronic pedometer

Abstract

To realize miniaturization and detection of a walk state in which no arm is swung in an electronic pedometer in which at least a walk sensor is used in a state of being worn on a wrist. An acceleration sensor is disposed so that a sensitivity axis of the acceleration sensor is located in a range of 30Ω or smaller in a counterclockwise direction from the direction of 90Ω with respect to a longitudinal direction of a belt. A user of an electronic pedometer wears the electronic pedometer on his / her left wrist using the belt and starts processing for counting the number of steps by manipulating a manipulation portion, and also starts to walk, thereby starting counting the number of steps. The user checks the counted number of steps and the measured time period based on displayed contents on a step number display portion and a time display portion of a display portion.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an electronic pedometer for measuring the number of steps by detecting a walk of a person or the like. [0003] 2. Description of the Prior Art [0004] Heretofore, there has been developed an electronic pedometer for measuring the number of steps of a user by detecting a walk of the user using a walk sensor. [0005] A watch type pedometer which is used by being worn on a wrist of a user like a watch has been developed as the electronic pedometer (refer to Patent Document 1 for example). [0006] With the above conventional watch type electronic pedometer, since a pendulum sensor is used, the number of steps can be measured in a normal walk in which a user walks while he / she naturally swings his / her arms. However, there is encountered a problem that the number of steps cannot be measured in a case where a user walks with his / her arm being fixed to a predetermined position (e.g., at the ear)...

AI Technical Summary

Benefits of technology

[0010] According to the present invention, there is provided an electronic pedometer having: a walk sensor for detecting a walk of a user to output a walk signal corresponding to the walk; calculation means for calculating the number of steps of the user based on the walk signal; and a belt with which at least the walk sensor is worn on a wrist of the user, the walk sensor being used at leas

Problems solved by technology

However, there is encountered a problem that the number of steps cannot be measured in a case where a user walks with his / her arm being fixed to a predetermined position (e.g., at the ear) without swinging his / her arms, for example, in a case where the user walks while he / she communicates with someone using his / her mobile telephone.

However, there is encountered a problem in that that a volume increases and circuits for amplifying signals from the sensors are required to be doubled in number because the two sensors are used, or when the electronic pedometer is driven in a time division manner in order to prevent such a situation, a time period required to drive the circuits increases, and hence the electronic pedometer of this type is unsuitable for the watch type pedometer.
